P0451 2007 Toyota Camry Code - EVAP System Pressure Sensor Range/Performance
Quick Answer
The Evaporative Emission System (EVAP) vapor pressure sensor, VSV for canister closed valve (CCV) and VSV for pressure switching valve are used to detect abnormalities in the evaporative emission control system. Common causes include Canister Pump Module (Faulty Evaporative Emission System (EVAP) Vapor Pressure Sensor ), EVAP system hose (pipe from air inlet port to canister pump module, canister filter, fuel tank vent hose), Evaporative Emission System (EVAP) Vapor Pressure Sensor harness is open or shorted. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
